lMlROVEMl-INT IN FA-NNING-MILLS AND SEPARATORS.

Specification forming part of Letters Patent No. 131,953, dated October 8, 1872.

To all whom it may concern: Be it known that I, DANIEL G. HILL, of Red Wing, in the county of Goodhue and. State of Minnesota, have invented a new and useful Improvement in Fanning-Mill and Separator; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and beingta part of this specification, in whichv Figure 1 is a perspective view of my mill and separator; Fig. 2 is an enlarged vertical section on the line a: x in Fig. 1; Fig. 3 is a perspective view of one of the adjustable side discharge-spouts; Fig. 4 shows its coveringboard Fig. 5 is a cross-section of one side of the shoe at the outer end; and Fig. 6 is a detail view of one of its clamp-screws and springs.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a machine for cleanin g, separating, and riddling all kinds of grain, its combination of parts being such that it may be adapted to the kind of work to be done and accurately adjusted to suchwork. The invention consists in the peculiar construction of an upper vibrating shoe, so arrangedthat a screen or several screens may it be adjusted therein atthe required position;

and, in connection therewith, a gathering-riddle and a grading-spout with an adjustable grain board or cover,'either of the two or both being used in the shoe, as the nature of the work may require; a divider adjustably pivoted across the space below the shoe;'and, in

- connection with aelower shoe, an adjustable spout and cover like those of the upper shoe,

the whole being arranged to operate as more fullyhereinafter set forth. I

In the drawing, A represents the frame of my machine;'B, the casing; O, the fan-shaft carrying the fan 0 D, a drawer in the lower part of the frame; and E, a hopper at the upper part thereof, 'in the under side of which is a slide, E, to regulate the opening at the throat, having atoothed rack, a, on its under side, with which a pinion, b, meshes, the rotation of whose shaft by a hand-wheel at the further side of the casing, as seen from Fig. 1, moves the hopper-slide, and thus regulates the flow of the grain from the hopper. F is the principal shoe hung in an opening at the rear upper end of the casing by metallic straps c. At its top innerend there is a grain-board, F, over which the grain falls from the hopper and passes thence to the first screen. notched post, 01, connects the outer ends of the grain-board to the lower frame-bar c below,

shoe are secured, their outer ends being held together by two rods, G, passing through them and provided with wing-nuts on their ing. 0n the right side of the shoe facing the rear end of the mill a strip, f, is partially embedded in a verticalgroove in the innerface of the shoe side, with two studs, 9, projecting through and abuttingagainst the washerbar h, against which the wing-nuts are screwed, so that the latter may force the strip f bodily inward. A spring, i, spirally coiled about the rods G between the outer side of the shoewall and the washer-strip, thrusts the latter outward when the nuts are'slackened. This arrangement enables me to clamp one or more screens, H, in the shoe, the inner corners of their frames being inserted in the notched posts and inclined-at any desired angle therefrom; also, the adjustable gathering-riddle I and'adjust-able spout J, the former beinginserted in the body of the shoe and the latter atthe lower outer end, its spout proper projecting at the further side of the casing. Its ends are provided with dowel-pins to more securely hold it in the shoe when clamped therein. It is also provided with a cover, K, which may disclose more or less of an opening parallel with its inner edge, as will be seen on reference to a similar one, J, Fig. 3, in which will be seen a vertical pin, t, at each end, and the cover K is provided with three pin holes at each end to receive the pin. The shoe F is vibrated laterally in a horizontal plane by the wellknown shake mechanism of a bell-cran k vibrated by a wrist on the end of the fan-shaft. Besides the shoe F there is an inclined shoe, L, at the bottom of the casing, which is cut away to make room for it above the drawer D, with two grooves on its inner faces. The back partds suspended by two links, 70, one at each side, pivoted to the inner side of the casing of the machine. Its inner end is suspended at each side by pivoting to the lower ends of and to these the inner ends of the sides of the threaded ends to hold the sides from spread- -ro'ds M, whose upper ends are r eccentrics N on the fan-shaft, and these rods near their middle to hey become levers, which, in the the fan-shaft, give the shoe a lonibration. In the upper groove of screen, 0, is slipped, and at the the spout J, Fig. 3, is inserted, ded with ribs l at the ends to enter ooves of the shoe. A divider, P, at its lower corners transversely asin g, its upper or thin edge being 1 any angle, and its position may y loosening and replacing the bolts it in the casing. The gatheringwill be noticed, is composed of a ted in the shoe, with three grainversely disposed therein, as shown Fig. 3, and the riddle may be so to deflect the grain to or from the wheat for market, the gatheringthe spout to the lower shoe are I d the divider inclined back far atch the heavy grain which falls he spout (toward the fan) and carn front of the mill, passing oil the 11 under the fan-case. For one st the spout to the upper shoe so throw out at the side enough of grain to have the remainder pass red grade, and if too much of the is so taken out it can be run i separator again.

s desired to make two grades for ust the spout as before, and also cover thereto, so that anything f the second grade will be carried ack end of the mill, while the N o. 1 be discharged at the spout.

heat for seed, take out the spout r shoe and put in the gatheringadjust its location so that thegrain rought to a line in such a way that parated by the divider below; extract its grainboards so as to take I of the falling grain as is desired;

then adjust the divider to make the separation required; put in the spout to the lower shoe so that it will catch what grain falls next beyond the divider; and adjust its cover so that it will carry ofi all light grain and foul seed at the end of the mill.

To clean oats for seed, adjust the gatheringriddle and divider to their proper positions, as before, so that grain or anything heavier than oats will be carried out in front, and the seed-oats will fall on the slide and go under the mill, while the still lighter oats will be caught in the spout and carried out at the side of the mill, and the lighter grains, seeds, &c., will be blown over the cover and out at the end of the mill.

The same principles, as explained in cleaning wheat or oatsfor market, will apply in cleaning all other kinds of grain for market or for seed, as this mill will not only divide grain by screening or riddling out the different sizes, the same as any other of its kind, bu from the arrangement of spouts, gatherer, and divider, will grade it according to its weight without reference to its size.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In grain sepa-ratmcs, a shoe, consisting of the walls F, grain-board F, notched post d,

frame-bar e, champing-rods G G provided with I suitable screw-nuts, the strip f provided with studs g, and the washer-bar h, substantially as described, and for the purpose set forth.

2. The adjustable gathering-riddle I, constructed as shown and set forth, clamped in the shoe F, as and for the purpose specified.

3. The adjustable spout J and adjustable cover K in combination with the shoe F, as and for the purpose set forth.

4. In connection with the shoe L, the adjustable spout J, and adjustable cover K, as and for the purpose set forth.
